RAILWAY-RAIL FASTENER.

Application led January 6, 1922. Serial No. 527,468.

T0 all fui/0771, tana-y concern.'

Be it known that l, Airuno Davies PRES- TON, a subject of the King ofGreat Britain, and a resident of Claremont, VVesternAustralia,Australia, have invented' a new and Improved Railway-Rail Fastener, ofwhich the following is a full, clear, and exact description,

This invention relates to improvements in railway rail fasteners, anobject of the invention being to provide an improved tie plate, clampand spike which cooperate to securely fasten a rail in place.

An additional object is to provide a fastener which will tend to bracethe rail against lateral and vertical strains set up by a passing trainand permit the variation of gauge and adjustment which may be requiredfrom time to time.

Another object is to provide a fastener of this character, which'willprevent the timbers from being out into and. being destroyed by Contactwith the tie plate, or in other words, to provide a tie plate which willcause the tie to be evenly compressed under-*the weight of train loads.

Still another object is to provide a railway railfastener in which arail may be removed and replaced without pulling the spikes.

` Further objects are to provide a device of this character, which willbe simple and practical in construction, strong, durable and ellicientin use, and which can be economically manufactured and installed.

With these and other objects in view, the invention consists of certainnovel features of construction and combinations and ar-v rangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings:

Figure l is a view in transverse section on the staggered line l-l ofFigure 3 through a railway rail showing the rail supported in appliedposition by my improved fastening devices;

Figure 2 is a view in section on the line 2-2 of Figure l;

Figure 3 'is a top plan view of Figures l and 2;

Figure 4l is a fragmentary sectional view illustrating the manner ofdriving the spikes into the ties; and

Figure 5 is a view in transverse section showing my improved fasteningdevices retaining a fishplate in position.

Referring in detail to the drawings, il represents a conventional typeof railway tie. A rail 2 is supported above the tie upon a tie plate 3.llt will be noted that the tie plate includes a flat under face bearing`against the tie and serving to evenly colnpress the same under the loadof a passing train. The flat face of the tie plate prevents injury tothe tie.

The tie plate includes flanged side edges such as l for a purpose whichwill hereinafter appear. The tie plate is secured to the tie by means ofmy improved spikes designated by the reference numeral 5. The spikes areround in cross section and include adjacent their upper ends taperedshoulders such as 6, which fit into tapered openings 7 in the tie plateholding the tie plate against movement and coupling` the saine firmly tothe tie. Above the shoulders G, the spikes include a screw threadedportion 8 and at their extreme upper ends are square in cross section,as indicated at o 9 so that they may be conveniently gripped by aSpanner wrench.

Clamping plates l0 include base flanges ll abutting against the flangese of the tie plate and beveled clamping flanges l2 which overliel thebase flange 18 of the rail 2. The clamping members are bored to receivethe reduced upper ends of the spikes 5 and the clamping flange 12 of onemember preferably overlies the base fla-nge l1 of an adjacent member.The flanges are held in place by gaskets lll and nuts 15 screwed ontothe upper end of the spikes 5.

lt will be readily seen that lateral strains on the rail 2 aretransmitted directly to the flanges 4f of the tie plate 3 through thenu:- diuiu of the clamps 10. llt will also be anw parent that the nutsand gaskets may be removed permitting removal of the cl inping platesand rail without disturbingthe position of the spikes 5.

The peculiar conformation of the upper ends of the spikes 5 permits themto be driven home by the use of a suitable tool without injuring theirthreaded portion. A drivingcap such as 16 shown in Figure t, may beapplied to the upper end of the spikes and will bear against the uppersquared ends of the spikes and against the tapered shoulders 6 therebyallowing them to be driven home without injuring the screw threadedportion of the same. The spike holes in the ties arepreferably drilledat the mill so that there is no danger ofrsplitting the ties byadrivinghome the spikes. lNhen it is necessary to remove the spikes they may beeasily driven through intothe ballast and new spokes of slightly largersize inserted. i

In Figure 5, I have merely illustrated a slight modification which showsanother use of the clamps 10. The clamps in thisinstance are used tosecurely clamp the base flanges 17 of fishpiates 18 at the junction oftwo rails. The clamps 1 are supported upon the iianges 4 of the tieplate 3 when used for holding` the fishplates and an additional `jointtie plate 19 of greater width than the plate 3 is used to support theplate 3 and is provided with lateral flanges 20 bracing the plate 3against lateral strain. It will of course be necessary to use'somewhatlonger spikes in connection with this form Vof fastener.

Although I have illustrated certain of the preferred embodiments of theinvention, it will be evident that various slight changes andalterations might be made in the general form and arrangement of theparts described without departing from the invention, and hence I do notwish to limit myself to the precise details set forth, but shallconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of the appended claims.

`I claim:

1. In a railway rail fastener, the combination with a tie plate and arail supported thereon, of clamping members on the plate includingfianges overlying the rail base and eachother.

2. In a railway rail fastener, the combination with a tie, a tie plateand a rail supthe tie and including tapered `shoulders lo `cated abovethe tie, said tie plate having recesses therein receiving the spikes,the walls of said recesses being tapered to seat firmly on saidshoulders, and rail engaging means -retained against movement on theplate.

3. In railway rail fastener, the combination with a tie, a tie plate anda rail supported on the tie plate, of spikes driven into the tie andincluding tapered shoulders located above the tie, said tie plate havingrecesses therein receiving the spikes, the walls of said recesses beingtapered to seat firmly on said shoulders, and rail engaging meansretained against movement on the plate, said rail engaging meanscomprising clamping members, sidelanges on the plate cooperatingwiththerail base to prevent lateral movement of the clamping members,said clamping members including overlapping flanges. i

4. In a railway `rail. fastener, the combination with a tie, a tie plateand 4a lrail supportedy on the tie plate, of spikes driven into the tieand including taperedshoulders `located above the tie, saidtie platehaving re cesses therein receiving `the spikes, the walls of said'recesses being tapered to seat rmly on said shoulders, rail engaging'means retained against movement on the plate, said rail engaging meanscomprising clamping members, side flanges on the plate cooperat-V ingwith the rail base to prevent lateral movement of the clamping members,said clamping members including overlappingI flanges, said clampingmembers being bored to receive thespikes, and nuts screwed-onto theupper ends of the spikes retaining said members in clamping relation toltherrail and to eachother.
